Description

 

To use the model P438USA, connect the two terminals in series with a load circuit that draws between ten milliamperes and three amperes. Connect to any voltage between 24 and 240 volts either AC or DC, set the 10 DIP switches to the required delay, and apply operating voltage. When the operating voltage is applied, a small amount of current will flow through the load and the timer. At the end of the delay period, the model P438USA turns ON and full load current is permitted to flow.
